Put a bale out in front of your place by the road, with a "for sale" sign on it. Should b able to sell your hay in about ten minutes, if anyone with livestock drives by.

Seriously, craigslist. Depending on your price, and what you are selling, should not b too hard. You might have to select your buyer, to be sure the deal goes as planned. Actually you might get it sold right here to someone in Illnois or missouri. I would not haul it all the way to Ok. I'm assuming you are east of Indy Indiana. ?
